| Abstract: | An algorithm to construct compactly supported semi-orthogonal wavelet packets of L2(Rs) is presented.. We have a wide choice of the decomposition coefficients in our construction, furthermore the wavelet packets are generalization of the basic wavelet packets. With these packets. We can choose the various bases of L2(Rs) flexibly. |
